Abstract (en)

[origin: WO9744691A1] A method and apparatus for cutting optical fibre are provided which can cut optical fibre smoothly and perpendicularly to the axis of the optical fibre. A ferrule (21) is held by a holder (14), which is supported inclinable with respect to a body (12) of the cutting apparatus (11), and an end of an optical fibre (20) projecting from an end surface of the ferrule (21) is held by a clamp (16) to apply a tension force. The holder (14) is inclined to bend the optical fibre (20), and a cutting blade (28) is arcuately moved, while abutting against an outer periphery of a base inside of the bent portion of the optical fibre (20), to form an arcuate notch (20a). Thereafter, the holder (14) is inclined in a reverse direction to bend the optical fibre (20) in a reverse direction to thereby cut the optical fibre (20).
